Jennifer Lopez & Casper Smart Take Relationship to Twitter

Casper Smart and Jennifer Lopez are finally speaking out about their relationship ... in 140 characters or less on Twitter.

The 24-year-old backup dancer took to his Twitter account last night to wax poetic about love.

"Age, status, n opinions of others are irrelevant," he tweeted. "Our hearts are endless and our souls infinite........... Our ages are mere reminders of the hours logged on this earth and the precious time remaining."

Smart continued, "We should all honor our time here by indulging our passion and dreams. So, close your ears and open your hearts; Love and be happy!"

Jennifer echoed his thoughts on her own page ... by re-tweeting all of his messages.

The two also made some more public displays of affection this week, after they were spotted getting cozy on the set of J.Lo's next music video.
